Best SEO META Description for forum topics

[Peter264]

What would be the best SEO META Description tag for forum topics on a forum type website?

I can think of a few options so far

1. Snippet of first post.
2. Title of the topic with templated trailing text
3. Remove description tag completely

Your thoughts and suggestions are greatly appreciated.

Personally I would make it the first post in the thread. When searching and arriving on forums, people are generally looking for a specific  bit of information which is answered in that thread. Often the first post is a question, so if you can get that question to appear in the meta description in the SERPS, the user is immediately going tho think "hey, that person has asked the same question I did" and click through.
